TO (all when it may cancel-It:

Be it known that I, IiIARRY T. Krxosnunr, a citizen of the UnitedStates, roslding at Keene, in the county of Cheshire, State of NewHampshire, have invented COItLiII new and useful Improvements in Toykiddo/r1 Trucks, of which the following is a description, referencebeing hao to the accompanying drawings and to the letters and figures ofreference marked thereon.

This invention relates to wheeled toys of that general class illustratedin Letters Patent issued to me on April 17, 1906, No. 818,261.

The principal object of the present invention is to improve and simplifythe construc tlon of the ladder-elevating means with a view offacilitating the raising and lowering of the ladder.

A further object of the invention is to provide a construction in whichthe ladder when lowered to horizontal position me rest by gravity on itssupport and is not placed under the stress or a spring; and a furtherobject in this connection is to provide a tension-developing deviceoperated by contact with an obstacle, by hand or by any other means, toeffect the raising of the ladder after the bumper starts to move.

A still further object of the invention is to provide a device of thisclass in which an inertia-wheel is eniploycd a driving me dium in placeof a propelling-spring, so that the greater pressure exerted may beutilized to advantage in the raising of the ladder.

ith these and other objects in view, as will more fully hereinafterappear, the invention consists in certain novel features of constructionand arrangement of parts, hereinai'ter fully described, illustrated inthe accompanying drawings, and particularly pointed out in the appendedclains, it being understood that various changes in the form.proportions, size, and minor details of the structure may be madewithout departing from the spiiit or sacrificing any of the advantagesof the invention.

In the accompanying drawimrs, Figure 1 is a side elevation, partly insection. of a toy constructed in accordance with the invention, theladder being shown in horizontal position on the truck. Fig. 2 is asiniilar view of the front end of the device, the ladder being elevated.Fig. 3 is a detail perspecand the connections between the bumper and theladder. Fig. 4t

, is a view, similar to Fig. 2, showing the use of l r l l l l thedevice without an elastic connection, the parts being so arranged as topcrnit the direct rz'rising of the ladder by the operation of thebuniper.

Sintilar numerals of reference are employed to indicate correspondingparts taroughout the several figures of the drawmgs.

The truck proper is formed of stamped sheet metal or other suitablematerial, and includes longitudinal sills 1, mounted on suitable frontand rear wheel axles 2 and 3. The rear axle includes a driven memberthat is propelled by an inertia-wheel 4, the wheels serving to drive oneor both of the front wheels and propel the truck. At the front of theframe is a seat 6 for a wheelsman or chauffeur.

The longitudinal sills are provided with vei tically-arranged lugs 8,carrying a pivot pin 9, which may form one of the rungs of a ladder 10,and the rear end of the ladder is arranged to rest on a suitable archedsupport 11 near the rear end of the truck.

In the front portion of the frame is arranged a bumper, comprising asubstantially U-shaped rod 15, the looped end of which extends through asuitable cross-bar 16 at the front of the truck and is designed toengage with the wall, a chair, or any other object against which it maybe forced as the truck is propelled. The rear ends of the arms of rod 15extend through guiding-openings formed in a cross-bar 17, and these armsare provided with a number of notches 19, which when the bumper is movedrearwardly are i engaged by the walls of the guiding-openings in thecross-bar for the bumper in the real-most position. The two arms of thebumper are connected at their rear ends by a bar 20, from which extendsa rod 21 to a spring 22. This spring is preferably formed of wire, andits central loop is connected to the rod 21, while its arms are woundaround the pivot-pin or ladder-rung 9, and thence are extended rearwardto pass under the next adjacent rung of the ladder.

In the operation of the device, the bumper is moved out to the forwardposition by depressing the rear arms of the bumper until LllG notches 19are free from the walls of the guiding-opening in the bar 17. Thisforward movement relieves the spring 22, so that there will be no stresswhatever on the spring the purpose of retaining pressure exerted issufficient to permit the and the ladder will be free to assume a horilbetween the bumper and the ladder to elezontal position and rest bygravity on the vate the latter. support 11.
